Leners Patent No. 85,913, dated .rama/ry 19, lisce.

vnvmnovr:Mrnv'r IN FReEzINGLBox FOR znrsrr,l are The v,Stzltiedule referred to in these Letters Patent and making pat of the same.

. Be it known that I, ummm Davis, of Detroit., in the county of Wayne, h the State of Michigan, have inyented a new and improved FreezinglBox or Pan'for Freezing Fish and Meats; and I do hereby declare that the following is a full and exact description thereof', reference being'had to thc.- accompanying drawiuga'and to the letters of reference marked thereon.

My invention consists in the construction of a thin sheet-metal pan or horiz in two sections or parts, one

made to slide over the ther, the object being to place 'the i'ish'or meat into one part of the box or pan, and slide the cover, or the other part of the box, on to or in contact with the thing be frozen, in order that the box, when placed in thg freezing-chamber, and in contact with the freezing-mixture, may have its contents quickly frozen.'W By reason of having the box so con-- structed, itin pable of expanding or contracting, to accommodate the size of whatever may be placed in'the box or pan, and the top and bottom always be in contact with the thing to be frozen.

Toenable others skilled in the art to makeand use my invention, I will describe its construction and operation;

. Figure l represents a section of my box or vpan in perspective, purposely` left open at the side, and

Figure 2 is a' cross-section, showing the two parts,

- in which Arepresents the bottom part, made of galvanized sheet-tin or galvanized iron and B, the top or cover of thesarne metal.

The bottom part of the box A is made in quadran- I f. gular form, with the sides. and ends extending" high enoughto receive'the smallest size of iish, or thing to be frozen; and the cover or lid B is made in the same manner and form, but j ust enough larger to closely slide over the part A, and on to whatever is placed in part A to be frozen.

Fig.- 2 represents the box in blue color, when it is contracted to its smallest capacity, and the red lines "show the cover raised, s o that a larger fish, or thing may be placed therein, which construction obviates the necessity of having so many dierent sizes of boxes, to

\ accommodate the different sizes of things to be frozen.

It is necessary, for a more complete operation of freezing the contents of the box, that the sides, or top and A bottom of y he box should always be in contact with the frozen, andY especially so in freezing fish, which should be frozen as quickly as possible after being taken can be more easily and thoroughly scaled and dressed than when not frozen.

The size of the bex'is to be varied according .to the size of what is to befrozen in it, but of such size that --thc cover will alwayscome in contact with the contents. i

After the {ish or other thing to be frozen is placed in the box, as above described, the box, with the' fish, is

"` placed in a reezingnamber,or in any box 'or chestfinlayers, covering eachlayer with any freezing-mixture,

one-inch, more or less, indepth, until the chamber orbox is lled with the freezing-boxes or paps and freezing-mixture. -Ice and salt are commonly used as the freezing-mixture, but any other mixture that will freeze the fish, will answer as well.

When the fish or other things are sufficiently frozen p. and solid, which usually requires from thirty to fifty minutes, they should be taken out of the freezing-boxor pan, and placedl in a keeping-chamber or house, where the temperature is constantly kept from six to ten degrees below the freezing-point, Where they can safely be kept as long as desired. l

It -will be seen that this construction of freezing-box or pan iis necessary vin order to keep the freezing-mixture from entering the box-Where the iish is, when it melts, as more or less of it will, which would, if perlnitted tov enter the box, damage the contents and render them worthless. i

I alu aware that boxes made of paper and wood have n -been constructed so that one part freelyslides over the other, and I do not broadlyclailn such box, as it would l not answer my purpose; but

Patent, is-.

T-he freezingbox or pan, when constructed andfused in the manner and.' for the purposes substantially a herein described. l
